“…21 ka) and reached similar limits to those of the Pleistocene everywhere except in Europe, where the North Sea and considerable parts of the Kara and Pechora Seas remained open (Ehlers and Gibbard 2008). Phylogeographic studies of Arctic-boreal fauna often detect population genetic signatures that coincide with glacial reconstructions (e.g., Weider and Hobaek 2000;Hewitt 2004;Hickerson and Cunningham 2006;Bigg et al 2008;Maggs et al 2008).…”

Biodiversity and phylogeography of Arctic marine fauna: insights from molecular tools

The last decade has seen an increase in the frequency and breadth of application of molecular tools, many of which are beginning to shed light on long-standing questions in biogeography and evolutionary history of marine fauna. We explore new developments with respect to Arctic marine invertebrates, focusing on molecular taxonomy and phylogeography-two areas that have seen the most progress in the time-frame of the Census of Marine Life. International efforts to generate genetic 'barcodes' have yielded new taxonomic insights and applications ranging from diet analysis to identification of larval forms. Increasing availability of genetic data in public databases is also facilitating exploration of largescale patterns in Arctic marine populations. We present new case-studies in meta-population analysis of barcode data from polychaetes and echinoderms that demonstrate such phylogeographic applications. Emerging patterns from ours and other published studies include influences of a complex climatic and glacial history on genetic diversity and evolution in the Arctic, and contrasting patterns of both high gene flow and persistent biogeographic boundaries in contemporary populations.

“…Several studies of Wsh with high dispersal capabilities either due to a long larval period and/or high adult mobility reported the absence of population diVerentiation along the west European shore (e.g. Almada et al 2008;Daemen et al 2001;Debes et al 2008;Hickerson and Cunningham 2006). In contrast, several other species, namely of estuarine Wsh, display diVerences among populations in the same geographical area.…”

Phylogeography and demographic history of Atherina presbyter (Pisces: Atherinidae) in the North-eastern Atlantic based on mitochondrial DNA

et al. 2009

A fragment of the mitochondrial control region was used to assess phylogeographic patterns and historical demography of the sand-smelt Atherina presbyter in the North-eastern Atlantic, covering its geographical range. A striking result is the highly marked diVerentiation between the Canary Islands population and western European ones. A genetic structure among European populations of A. presbyter was revealed, with a pattern of isolation-by-distance or a gradient eVect at a scale of hundreds kilometres, an uncommon pattern likely related to the biological and life-history traits of the sand-smelt. The northern European populations present a much lower genetic diversity when compared to southern populations, which is consistent with a recent colonization from southern populations. The results showed signs of Pleistocene signatures, with the population age estimates for the European populations being clearly older than the Last Glacial Maximum (18,000 years bp). Nevertheless, paleotemperature reconstructions show that the sand-smelt could not have inhabited the western European shores during the last glacial phase.

There is also evidence, however, that other amphi‐Atlantic coastal and intertidal organisms, such as fishes (Hickerson & Cunningham 2006; Bigg et al. 2008), cirriped crustaceans (Wares & Cunningham 2001), and bivalve molluscs (Wares & Cunningham 2001; Maggs et al.…”

Colonization and/or mitochondrial selective sweeps across the North Atlantic intertidal assemblage revealed by multi-taxa approximate Bayesian computation

et al. 2010

Intertidal and subtidal communities of the western and eastern coasts of the North Atlantic Ocean were greatly affected by Pleistocene glaciations, with some taxa persisting on both coasts, and others recolonizing after being extirpated on one coast during the Last Glacial Maximum. In the original spirit of comparative phylogeography, we conducted a comparative analysis using mtDNA sequence data and a hierarchical approximate Bayesian computation (ABC) approach for testing these two scenarios across 12 intertidal and subtidal coastal invertebrates spanning the North Atlantic to determine the temporal dynamics of species membership of these two ephemeral communities. Conditioning on a low gene-flow model, our results suggested that a colonization or mitochondrial selective sweep history was predominant across all taxa, with only the bivalve mollusc Mytilus edulis showing a history of trans-Atlantic persistence. Conditioning on a high gene-flow model weakened the support for this assemblage-level demographic history. The predominance of a colonization-type history also highlights concerns about analyses based on single-locus data where genetic hitchhiking may be incorrectly inferred as colonization. In conclusion, driving factors in shifting species range distributions and membership of ephemeral coastal communities could be species-specific environmental tolerances, species interactions, and/or stochastic demographic extinction. Through a re-examination of a long-standing question of North Atlantic phylogeography, we highlight the flexibility and statistical honesty of using a model-based ABC approach.
